The Schneider Electric A9D69625 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — one module that combines a B-curve MCB and a 300 mA earth-leakage trip in a single 36 mm wide, 1P+N package. It clips onto a DIN rail (4 x 9 mm pitches) and is rated for 25 A at 220…240 V AC, 50 Hz, with a 6 kA breaking capacity (Icn) per EN/IEC 61009-2-1. The thermal-magnetic trip unit gives a B-curve magnetic threshold of 3…5 x In, so it's sized for general-purpose distribution and lighting circuits where inrush is modest. The integrated earth-leakage protection trips at 300 mA — a common sensitivity for whole-circuit or submain protection against ground faults, not personnel shock (that would be 30 mA).
The 36 mm width (4 pitches) is the standard single-module footprint for a 1P+N RCBO in the Acti9 range — it occupies one slot in a Schneider distribution board alongside other Acti9 devices. Terminals accept 1…16 mm² rigid or 1…10 mm² flexible at the top or bottom; tightening torque is 2 N.m. Wire strip length is 15 mm. The toggle gives local ON, OFF, and fault-trip indication. The 73 mm depth fits standard shallow enclosures.
